FAN2310AMPX

Overview

The FAN2310AMPX is a switching regulator manufactured by Fairchild Semiconductor, now part of ON Semiconductor. It is housed in a 34-pin QFN package (34LD, Clipbonded PQFN, TinyBuck 3, 5.5x5.0 mm). The device is lead-free and RoHS compliant with a Moisture Sensitivity Level of 1. It is classified as a switching regulator under ECCN EAR99.

Feature Summary

• Monolithic high- and low-side gate-drive IC
• Floating channels for bootstrap operation up to +600V
• Common-mode dv/dt noise canceling circuit
• Built-in under-voltage lockout for both channels

Applications

• Switching power supplies
• Motor drivers
• High-power DC-DC converters

Procurement Notes

Verify the exact ordering suffix against current ON Semiconductor catalogs due to integration changes from Fairchild. Confirm package dimensions and pinout compatibility during design-in. Check for updated datasheets reflecting the transition from underscore to dash nomenclature in official documentation.

Selection Notes

Select this component for applications requiring high-speed MOSFET or IGBT driving up to +600V. Ensure input logic levels match the 3.3V or 5V requirements. Verify thermal management capabilities for the QFN package in the target enclosure environment.

Part Context

This component belongs to the FAN23xx series of gate-drive integrated circuits. It is designed for high-performance power conversion systems where noise immunity and fast switching speeds are critical. The integration of noise canceling techniques distinguishes it from standard gate drivers.

Replacement Considerations

Check ON Semiconductor website for updated part numbers replacing Fairchild underscores with dashes. No direct substitute part numbers are confirmed in public data.
